GRATE.

SPECIFICATION formingpart of Letters Patent No. 411,391, dated September1'7, 1889.

Application filed May 8, 1888. $erial No. 273,259. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM J. Owens, of Utica, in the county of Oneidaand State of New York, have invented a new and useful Improvement inGrates, of which the following is a specification.

This invention relates to the construction of furnace-grates and themeans of dumping or removing the same from the furnace.

The object of my invention is to provide a grate that can be readilyinserted or removed from its position in the base of the furnace; and myinvention consists in the construction and combination of parts, ashereinafter described and claimed.

In the drawings which accompany and form a part of this specification,Figure 1 is a plan view of the grate as it rests in the furnacebase, theenlarged and sleeved portions of the bars being broken away, thesupports and hangers for the lugs 1' being omitted, and the cap-strip nbeing removed from position. Fig. 2 is a detail side elevation of thehanger and means for supporting the forward portion of the grate. Fig. 3is a face or front view of the grate and base. Fig. 4 is a detail sideview of one of the saddles for supporting the rear trunnions of thegrate,.a portion of the base being also shown. Fig. 5 is a side View ofone of the toothed sleeves. Fig. 6 .is a section of the same 011 line yy of Fig. 5. Fig. 7 is a section of the same on line '00 x of Fig. 5,showing the hexagonal portion of a bard therein; and Fig. 8 is aperspective view of one of the bars (Z complete, its toothed sleevebeing omitted.

The f urnace-base casting a is provided near its rear portion with twosaddles e, to receive the trunnions g, which project from the circularportion is of the grate-frame. Cleats or bearings h are secured to thecrown portion of the base-casting, and these receive the ends of a barj, having hangers c, as shown in Figs. 2 and 3. These parts are omittedfrom Fig. 1, as hereinbefore described, to more clearly show theconstruction of the grate proper.

The hangers a receive and support lugs t', projecting from the frontportion Z of the grate-frame. This front port-ion has a front bar 12 andjust behind it a cross-bar m, the for mer having holes 25 to allowaccess of acrank portions of bars (1 lying within circular frame 7; aremade hexagonal and provided with longitudinal grooves or channels 0,while similar grooves f are provided in the interiorof the sleeves r,which have projections or teeth 3. Said sleeves are adapted to fit thehexagonal portions of bars 0?, so that grooves f and n will formair-channels, as shown atf in Fig. 7.

In putting the grate together the toothed sleeve is slipped onto thehexagonal portion of bar d, the rear end of said bar is inserted in itsplace in bearing u, and the round portion of the bar is then dropped toits bearing in cross-bar m. All the bars d are so placed and with theirgear-Wheels o meshing, and the cap-strip n is secured in place. Then thegrate-frame is passed into the open front of the furnace-base and itstrunnions g lifted into their seats in saddles e by means of a hook orother suitable means. The front portion of the frame is then lifted, andas this is done the lugst' strike the lower portions of hangers 0, pushthem to one side until the lugs have been lifted sufficiently so thehangers 0 can swing back to vertical position, when the frame can belowered until its lugs 2' rest in their seats in the hangers, as shownin Fig. 2. The grate can be removed by the reverse of this operation, itbeing understood that in removing the front portion of the frame isfirst lifted and the hangers swung out of the way by any suitable means.

hen the frame is removed, any of the parts can be repaired or renewed.For example, a new toothed sleeve can be supplied to a customer at anytime and can be inserted without taking the furnace apart.

It may sometimes be desirableto have the front ends of bars (1 projectbeyond the front bar 19 to rend er them more accessible for turning. Inthis case I prefer to provide the front bar 19 with depressions insteadof holes 25, so the bars (1 can be readily removed by first liftingtheir front ends.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is

1. In combination with a f urnace-base, a grate suitably supported atits rear end and having a 111g 1' on each side of its front portion, anda rocking bar j, having hangers c c to receive and support the lugs 'i,su bstantially as described.

2. In combination with a furnace-base having saddles e e at its rear, agrate having trunnions g to fit said saddles and lugs '6 on each side ofits front portion, and a rocking bar j, having hangers c c to receiveand sup- WILLIAM J. OWENS.
